DottaandPaperclip 374a918d67 fix(runner): retain qualified OpenCode artifacts for cold recovery (#19622)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native recovery must keep admitted provider state and useful
workspace files.
> - OpenCode binds its saved session to exact executable paths and
hashes.
> - A replacement image can remove those files even when session data is
saved.
> - Retaining a manifest alone cannot restore the missing launch files.
> - This pull request saves the qualified files before provider work and
restores the same owned paths.
> - The benefit is cold continuity without relaxing the Runner guard or
replaying a prior turn.

## Linked Issues or Issue Description

Refs #19558. That fix retains the selected pack for ordinary
continuation. This change adds durable file retention for a cold
allocation. Related #19487 adjusts the admission budget; it does not
retain launch files. A search of open and closed OpenCode cold/durable
artifact PRs found no duplicate.

**What happened?**

A saved OpenCode session could outlive the image that supplied its Node
executable, proxy, and native executable. A new image supplied different
bytes. The Runner then correctly refused the changed launch profile. The
saved harness did not contain the old files.

**Expected behavior**

Core must save qualified launch files before the first turn. It must
restore those exact files under the same owned account and absolute
paths. Unknown ownership, missing files, and changed hashes must still
stop recovery.

**Steps to reproduce**

Start an admitted remote OpenCode session. Save its workspace, encrypted
checkpoint, and harness data. Destroy the original allocation and
controller files. Restore into a new allocation with an image whose
qualified proxy has different bytes. Resume the same session. The new
opt-in local qualification command automates this path with actual
OpenCode and a local synthetic model.

## What Changed

- Store company-bound, encrypted launch objects and canonical run/backup
references. Generate migration 0438 through the normal database
workflow.
- Stage qualified Node, proxy, and native OpenCode files under a private
content-addressed OS-account home. Record the account UID and exact
launch paths. Preserve the Rust profile guard.
- Gate first provider work on durable capture under the current native
claim. Bound Stop/deadline waits while the actual late transfer keeps
its worker and scratch ownership until settlement. Restore cold caches
with verified staging and atomic rename. Keep live reattachment and
historical image-rooted sessions on their existing paths.
- Reuse bounded canonical expiration owners. Atomically fence old
checkpoint authority with a strict company/run-scoped retirement marker
before external deletion. Keep its indexed cleanup anchor across failed
deletes and restart. Preserve earlier resume handles and reject later
header or source-consumer writes. Add no idle scan or network call
inside a transaction.
- Add storage, race, executor, filesystem, and actual Rust resume
regressions. Add the opt-in local Linux qualification command and
operating limits in `doc/opencode-cold-recovery.md`.

## Verification

- RED before repair: real PostgreSQL/AES cold restore lacked the launch
files; normal executor preparation chose the new image pack. Separate
regressions exposed lost upload receipts, missing cache repair,
last-owner retirement, an account-UID mismatch, and a resume-handle race
during external deletion. Each expected failure was captured before its
repair.
- Local qualification before the final master integration: 1,169
executor tests, 233 storage/archive/admission/expiration tests, all
seven server typecheck layers, migration safety, and the actual Rust
cold-resume test passed.
- The maintained Linux command passed with two cached immutable
Paperclip images whose proxy hashes differ. It removed the original
account/controller trees, restored the production published cwd under a
new lease, resumed the same actual OpenCode session, kept a useful file
and prior model context, and made one new synthetic model request. No
external model call or network was available in either container.
- The object-store fixture uses real encrypted StorageService streams
with an independent owned local directory. It is not hosted S3
acceptance or a complete task HTTP/actor workflow. Historical tasks
still require normal effects reconciliation and recovery after
deployment.
- Review regressions reproduced partial-cache publication,
resume-versus-deletion, fresh-writer and source-consumer resurrection,
and unbounded Stop/deadline waits before each repair. They now pass
through real filesystem, encrypted storage, PostgreSQL, and SDK
boundaries. File validation is split from database ownership (384/831
source lines).
- Clean runtime head `aadab7acc69ff959678030db46ffe2dcfbefe28f`: the
maintained actual OpenCode cold qualification passed with `dirty:false`.
It preserved the provider session and recorded launch paths, restored
useful workspace content and prior model context, and made exactly one
resumed synthetic model request. The 314,560,000-byte launch capture
took 23.118 seconds; the later harness was 833,536 bytes. Subsequent
repairs change backup-reference retirement and governed continuity-cache
classification; capture, restore, launch, and published-workspace inputs
are unchanged, so that runtime receipt remains scoped to those paths.
The continuity-break consumer is verified separately.
- Retention repair `c14d386cecf7123257918ba6a8d47307df2da397`: 68/68
affected real PostgreSQL/AES storage tests and 15/15 focused executor
authority/admission cases pass. All seven server typecheck layers pass
(source layers and unchanged test shards, with the final 590-file test
layer repeated after fixture edits). All review threads have
evidence-backed resolutions. Its subsequent CI caught the separate
lifecycle-classification gap described below. The refreshed Paperclip
review reported paused work, not a completed new review.
- Final head `4d1cd3e3309e328b11abc85adc6d78c6d0c7f55d`: all 19 focused
root-entry/executor cases and all three source declaration layers pass.
[Greptile reviewed this exact head at
5/5](https://github.com/paperclipai/paperclip/pull/19622#issuecomment-6695984874).
Final-head [CI
verification](https://github.com/paperclipai/paperclip/actions/runs/42308908167/job/128214100339)
passes: 60 successful checks, five conditional skips, and the explicitly
neutral paused Paperclip review. No check is pending or failing.
- CI also caught the launch cache missing from the session-root
lifecycle contract. Both the writer scan and a real governed-replacement
consumer failed locally before repair: old launch bytes remained in the
active root. The cache now archives with the prior session state; the
consumer verifies exact bytes are preserved in the archive and absent
from the active root.
- The latest review found that backup retirement could delete an
independent run pin while a selected session retained the checkpoint. A
real PostgreSQL/AES regression failed before the repair. Backup-only
ownership now uses a NULL-safe exact backup predicate; the run pin
belongs to fenced checkpoint expiration. The regression verifies
checkpoint decryption and launch-file restoration after pending-backup
cleanup, followed by deletion only after removing the final resume
handle.
- An executor first-session case checks new-session durable capture
through the real capture helper and receipt propagation into the actual
harness manifest at the backup boundary. Real storage cases verify the
run-profile receipt and canonical backup/run pins.
- Sequential closure reuse and simultaneous first admission are
different scopes. A deterministic two-uploader test measures both
independent uploads, one verified ready winner, loser-only deletion, and
usable restoration for both runs. Each capture is bounded to 512 MiB and
five minutes; up to three pending receipts per run are retained. There
is no claim of global single-flight capture or a company-wide egress
bound.
- Earlier optional warm-ownership verification encountered missing local
binaries. After exact-source setup, all nine ownership assertions
passed; two other suites encountered local PostgreSQL setup/teardown
contention, so those interrupted attempts are not passes. Required
current-head CI supplies the broad final coverage. No deployment or
hosted historical recovery is claimed.

## Risks

- This adds two tables and a forward migration. The file object is
bounded to 512 MiB. Capture adds one initial transfer; later harness
archives exclude those large files. Company-scoped ready objects are
shared and retained until the last canonical owner retires. Concurrent
initial admissions can duplicate bounded transfers; each keeps
independent ownership and cancellation rather than waiting on another
controller. A continuity break retains the controller cache with its
prior state until normal session-root cleanup, adding up to one bounded
launch closure per retired state.
- Cold continuity requires the same qualified Linux platform, supported
runtime dependencies, owned account UID/home, and published absolute
cwd. A mismatch fails closed. No alias or Rust guard change is included.
- Existing image-rooted profiles have no retained file object. This
change cannot backfill missing historical binaries. A fresh governed
session must reconcile prior effects first.
- Live reattachment does not read artifact objects. Storage or
provenance failures before a new turn hold admission. They do not grant
new execution, model, tool, or replay authority.

## Model Used

OpenAI Codex, GPT-6 family, with reasoning, repository tools, code
execution, and local browser tools. The exact served model ID and
context window are not exposed in this session. No claim is made for
unavailable model metadata.
